Voting Finished + Sub Giveaway in Discord

We’ve wrapped up the voting for the fan art contest, you can see the results at the bottom of the page here.  These arts all came out so great! I’m hoping to do another fan art contest like this again in future at some point.

Sly is also sponsoring a really quick game sub giveaway in our Discord right now. If you’re seeing this late, don’t worry too much– rumor is there will be another one in future~ 😉

(Open to all 18+ persons, no purchase necessary to enter)

Fan Art Contest Entries (vote!)

We received three entries into the contest, which means each person who entered will receive a prize!

Thank you so much to our fan artists, I absolutely love your artworks!

Active backers can vote on their favorites in the Researcher Intranet.  (The entry with the highest number of votes at the end of two weeks will receive their first pick for prize.)

Update:  Polls are now closed!  Results here, all artists will be contacted shortly.  During polling, I saw each entry enjoy a period of being either in lead position or tied for lead position, so it was anyone’s game.  Each of these artworks are great, so thank you again to our entrants!

r41.5 – Save/Load & Wyvern TF

Naga Queen is excited about the new build!

My initial plan for this release was to get right back into content updates.  I got started with a nice bit of planning for the content update, and then remade the text editor in the new engine so I’d actually be able to get story text back into the game.

Unfortunately, mid-development, I started to realize just how broken the old Flash version is after hearing more and more bug reports for it.  There’s a lot of subtle, game breaking bugs in it (like in the dino chapter where depending on which Flash runtime engine you use, Hanako will give you inaccurate directions and make the chapter unbeatable).

The new web version is much more stable and fixes those problems, and it’s the version of the game I strongly recommend people to use for that reason.  One big thing that will help with more people using the new version is getting save/load ported over so you won’t have to rely on Flash to access save files.

So, here’s the new updates in this build:


The main feature of r41.5 is reintroducing save/load — a (perhaps) surprisingly large task given how everything ties into the save/load system.  The new save/load system also includes new save file slots for subscribers, for a total of 20 slots.  More slots support has been frequently requested, so hopefully comes in handy!

The system should be backwards compatible with old save files from previous Flash versions of the game.  Under the hood, the format is pretty different, although as much as 10x more space-efficient versus the old method.

If you have an old save file that won’t load, or a new one that doesn’t seem to save/load correctly, please report it as a bug and attach your save file.  (Remember, you don’t even need to register a separate account on the bug tracker, it uses your existing one 🙂  If the fields on the bug report confuse you, most of them you can leave blank.)

Wyvern TF

In order to prevent the game getting into a weird state with save/load, I also went ahead and ported the TF part of the Wyvern DLC.  Note that it doesn’t include the monster part of that since that was implemented as a mod, and modding hasn’t been implemented yet.  Even without, this is still a quite fun TF to play.  Until that content comes online, the second easiest way to get knocked up as a Wyvern is to find the Octomaid in the debug rooms.

Login System

Also to support save/load, the login system has been added in the new engine.  This mostly is needed for players using the demo without starting logged in, who then decide they’d like to login mid-game so as to save their progress.

In that case, you’d see the new login screen:

Text Editor

The text editor is an important tool that I use to get text into the game and tested.  The first part of this release was spent getting this up and running so that I’d be able to eventually get game content added again.

Unlike the old Flash engine where the tool was limited to myself, the parse tester part of this tool can now be used by modders directly to test out your strings… though that may not be overly useful until modding itself is implemented again.  Still, you can check it out by pressing ` if you want to.



  • Support for much longer text on-screen (this involved writing a packet splitting system; fixes #83).
  • Self-test mode – now as part of automated builds, the game will self-test on a small collection of save files to flag potential issues.  This helped find a bunch of potential save/load errors before this build got released.  In future, I’d like to expand this to more areas of automated testing.
  • UI Windowing system to support the Text Editor.
  • When in water, don’t assume slugs are grinding against the floor since there may not be a floor. (Have them grind against themselves instead :3)
  • Frogs can now breathe underwater, and won’t produce visible slime when either in water or underwater (Fixes #67).
  • Added a quick search bar to the bug tracker header to quickly find issues.
  • Fixed bug where frog TF player description is missing player eyes description.

This build is now released in both full version and demo variants.

Fan Art Contest Reminder

Don’t forget there is a fan art contest going on now.  We’ve already had one lovely entry (thank you!), but we have three prizes to give out!

UPDATE – Hotfix

41.51 fixes a bug in this version that caused frogs to respawn in ch7 — thanks for the report!

A (Fan) Fan Art Contest

Our resident community member Sly is hosting an Underworld Fan Art contest!

Prize pool

Sly put together the following prizes for the contest. The winner will get their first pick, then the second person, then so on:

– A one month subscription to Underworld (Provided by Sly)
– A one month Discord Nitro Classic sub (Provided by Sly)
– A $25 Steam gift card (Provided by Skye)


All entries must relate to The Underworld in some way. Anything from simple mspaint doodles of characters to fancily lit full game scenes is great, as long as it has original artwork you made and is about the game.

All skill levels are welcome to enter (beginners welcome!).  This is intended to be a fun community activity, so don’t worry if you’re not a pro. 🙂

Ideally, if you can add a footer as described in the footer section of the earlier released fan art guide (basically linking to Underworld as well as your own site) it can be helpful for the game, but it’s not required!


All art must be submitted via this form by Feb 21, 2022 Noon US Pacific Time.

You are, of course, welcome to also post your art to FA/Twitter/wherever also.


After the submission deadline, all valid entries will be posted on the research blog. There will be a two week deadline for people to vote using the usual Underworld voting system.  Then prizes will be awarded from first place on down.


No purchase needed for entry.  Contest is open to all persons aged 18 and over.

Entries will be submitted under the User Generated Content License (same license as mods, this just allows me to reshare the art on the blog — you can still post your piece to wherever else you like, too!).
